srcrrrne em) Rns'rAR'rING MECHANTISM.

Application `filed December To all ywhom t may concern:

Be it known that l, HOWARD l). COLMAR, a citizen of the United States, residing at Rockford, in the county ot' Winnebago and State of illinois, have invented new and useiui improvements in Stopping and Restarting Mechanisms, of which the follown int;r `is a speciication.

This invention has particular, lalthough not exclusive reference to winders oi the class in which there is a Winder-tending mechanism. arranged to travel around the winder and operate upon the winding units. Winder ot this type is shown in Patent No. l,..07,977, dated May 28, 1918. The winder-tending mechanism disclosed in said patent is arranged to he automatically stopped `apen the completion of each round trip and to he automatically restarted after an idle period ott predetermined length. The Winder-tending mechanism is stopped and restarted by means acting upon switches included in the electric circuits that furnish current to the motor of the windentendingmechanism.

The object of the present invention is to provide stopping and restarting means arranged to act upon a clutch that controls the transmission of power from the motor to the mechanism for causing the Winder-tending mechanism to travel. the aim being to climinatc the necessity of starting the motor un der load since this is apt to produce sparking; at the motor brushes which is obviously objectionable because of the resulting increase oit lire hazard.

ln the accompanying drawings. Figure 1 is an eleva-tion section through a Winder showing. in side elevation, Winder tending'- mechanism and controlling means therefor. Fig. 2 'is a fragmentary side elevation of a portion of the controlling` means.v Fig. `3 is a fragmentary plan view oi' one end of the Winder showing the Winder-tending mechanism at rest at the beginning ot a round trip. Fig. 4- is a fragmentary horizontal section on an enlarged scale taken in the plane ot' line #4 of Fig. 8. Fig. 5 is a l"inementary side elevation of the mechanism shown in Fig. e., Fig. 6 is a fragmentary vertical se `tion on an enlarged scale taken suh-` 3, 1319. serial No. 342,259.

stantiallyin the plane of line 6 6 of Fig. l. Fig. '7 is a fragmentary horizontal section taken 'in the plane of line 7-7 of Fig. 6. Fig. y8 is a 'fragmentary vertical section taken on line 8 8 of Fig. 5.

`The invention is herein shown as ,embodied in a .machine generally` similar to the one disclosed in the l)fOre'-1n.e1i`itioned Patent No. 1,207,977. `lleference may he made to said patent 'for an .understandin,e` of the construction and voperation of the mechanism tro-operating witht-hose herein illustrated.

The winder-tendinf.,y mechanism is mounted upon an endless elevated rail 80 consisting' oi two straight parallel portions and semicircular end sections. rllhe carriage or framework ot the Winder-tending mechanisml consists of ahase or main section 88 and a ,dependinc'irame 89 rigidly attached to one end ot the hase. At one end of the hase 88 are ltwo ,rollers `90 arranged to run upon the rail 86. Adjacent to one o-f `the .rollers 90 is a guide roller 91 turning,` upon ya vertical axis and hearing uipon an endless guide rai`l92. Adjacent` to the other roller v90 is a pinion 98 'rotating upon a vertical axis and meshing with an endless rack 9d `arranged at the outer edge of the rail 8G. Guide rollers 05 `and 96 run along the 4inner edge oi? the rail 86 adjacent to the *roller 91 and the pinion 93, respectively.- The opposite end oil" the hase 188 is supported upon a roller 97. Then the ywinde'r-tending mecha.- nism reaches one end ofrthe Winder and the rollers f90 pass onto 'the semicircular rail portion at that end of the machine, `the hase 88 turns through an vare ot 180 as the rollers 90 traverse said semicireular rail sectiomthe roller 9T mot/ing onthe curved rail 98 to the other side of the Winder Atrnmeworlr.

Power to actuate the winder-tending mechanism and to cause said mechanism to travelv upon Vthe rail 86 `is supplied vby an elecn tric` motor 103 mounted 'upon `that end oi the hase 88 which is carried by `the roller 97. Power 4is commimicated from the motor 1053 to the pinion 93 and the mechanisms that operate on 'the winder units `by means comprising' a belt 203 Arunning over apulley 204 on the armature shaft andover a pulley 205 rotatably mounted on a shaft 206. Q07 is a sleeve is slidable along the shaft 206, but the shaft is connected to rotate with the ysleeve by means et a spline 210' (Figs. el

and S). ing' the shaft .fin expansion spring` 211 surround- 20ol is interposed between the shoulder 212 on said shattand a flange 2l?)` on the end of the sleeve 210, saidspringj serving' to holdthe clutch member 209 normally `in engagement with the clutch surface 208. y

lt is desirable that the Winder-tending mechanism shall be ready to opera-te upon the successive Winding` units promptly after the bobbins exhaust. The time required to empty a bobbin varies with the amountv of yarn thereon. :it is therefore desirable that the travel ot the Winder-tending mechanism shall be subject to control so that it may be variedwhen changes are made in the character oit the yarn being Wound. rlhe Windertending mechanism is therefore arranged to Wait at one end oi" the Winder framework after each round trip for such a length of time that the active bobbin of the ynext unit to be operated upon shall almost certainly be exhausted before the Winder-tending mechanism reaches it. The length ot the stoppage` oli' the Winder-tending,` mechanism is predef` f termined in accordance with the maximum Cil Cil

length of time necessary to unwind bobbins conte-ming` a given `size ot yarn spun rWith a given amount oi traverse and a given size of spinning ring.

p W7 hen the Winder-tending; mechanism has passed the Winding units located at one side ofthe machine, an element carried by the Winder-tonding` mechanism is caused to disengage the clutch. member 209 from the pul ley 205, thereby suspending;4 the travel ot the carriage 88 andstopping the mechanisms Vtor operating upon the units.` he element reterred to is an arm 700 S). Which is fixed upon a horizontal rock sha-tt 701 mounted on the carriage 88. 'lhe arm 700 lies in contact `with a pin 702 carried by a forli 703. Said :fork is supported in the framework of the Winder-tending mechenism for pivotal. movement upon the 704; and carries two studs 705 that lie at clutchr member 209 hired upon a sleeve'210. Said' arm 708 is pivoted on a bracket 710 attached to the stationary framework ot the Winder. rlhe arm 709 is tired upon a rock shaft 711 which is mounted in `suitable brackets in the Winder framework. A contractile spring;` 712 acting` upon the arm 708 normally holds the bar 707 in position to be engaged bythe varm 70. the action oi" said spring being limited through contact or an arm 713 on the shaft 711 with. a stop pin 711.. The bar 707 normally held against movement by means ot a pivoted latch 715 engagingthe arm 713; consequently, when the aim 706 strikes the end 01": the bar 707 the continuing' travel ot the carriage 88 causes the shaft 701 to turn, thereby throwing; out the clutch member 209, the end of the arm 706 sliding'alongl the top ot the bar 707 until the movement of the carriage 88 due to momentum ceases.

llxhen the Winder-tendine; mechanism is .to be again in operation. the latch 715 is disengaged from the arm 13, whereupon the springv 211.; acti. p; through the arm 700.7 overcomes the spring; 712, and moves the 707 upon the arms 708 and 709 downwardly until the arm 706 again assumes its rormal position.` fas the arm 706 moves into such position., the spring' 211 throws in the clutch member 2097. The means for disengaginp; the latch 715 'from the arm 713 will next be described.

directly connected to one of the cam drum is (not shown) of the Winder. Onthe shaft 710 1s lined a Worm 71.7 that meshes with trie Worm Wheel 718 which is ii ed upon .it 719. ylhe shaft 719 is supported in a 'i -f 720 which is mounted on the trameoit the Winder. F on the shaft 719 is a Worm 721 that meshes with a Worm Wheel 722 which is fired upon sleeve 723. To the lower end oi the is lined a friction clutch member 72st. A coactine' friction clutch member 725 is riqjidly fixed to one of a dish 726. i expansion and'torsion spring? 727 normally uolds the friction clutch me. ler 725 pressed against the clutch member 72e. @ne end oi:
